Sadly I changed all of those parts out about 4k ago.

I think it may be low on fluid and the click only goes away because when i increase / stay steady the oil is being thrown up on the disgruntled gear. I just purchased some so we'll see. If it's not that the only thing i can think of would be a chipped gear. That means either i'll be rebuilding a tranny soon or buying a new on... I'll reply on where once i test my oil theory.
